,c Application led November 28, 1922. Serial 110.303,738.

To all whom t may conce/m:

Be it known/that I, HARRY SEIGMAN, a citizen of the kUnited States, and resident of New York city, inl the county of New York and State of New York, have invented cer-` tain new and useful'mprovements in Razor Double Stropping Machines, of which the following is a full, clear, and concise description. c

My invention relates to razor double stropping machines, my more particular purpose being to produce a device of this character having ytwo strops, one made preferably of canvas and the other of leather, the device as a whole being so arrangedand adapted as to enable the operator to use lirst one'of the strops and then the other, upon an individual razor blade.

More particularly stated, I` seek to produce a small machine, operable by hand and made up tofsellat a moderate price, the machiney being composed of a relatively small number of parts of simple construction, so formed and arranged that either a single` razor blade or two such blades may be held within the machine at the same time, and either o r both of these blades subjected the two vstrops abovefmentioned; that is to say, the strop madeof canvas and the one made of leather.

Reference-is made to ythefaccompanying drawing forming apart of this specification, and in which-like reference `characters indicate like yparts throughout the several iigures.

Figurel is a substantially central vertical section through my device.

Y Figure 2 is an .end elevation of the mechanism appearing in Figure 1.

Figure 3 is a fragmentary side elevation of the same. f

Figure a is a fragmentary side elevation, showing my device as it appears while being changed for the purpose of substituting one strop for the other, for use upon a blade.

Figure 5 is a sectionon the line 5 5 of Figure 3, looking in the direction indicated by the arrows. f

Fi ure 6 is a fragmentary section showing the evice in use, after the change contemplated by Figure 4 is made.

Figure 7 is an enlarged fragmentary elevation, corresponding to the left hand p'ortion of Figure 3.

y A bail appears at 7, pair of ends 8, turned inwardly. Pivotally secured to these ends are a pair of bearing plates 9, made of sheet material. y of rocking plates are shown at 10 and 11, and are provided with edge portions 12, 13 each bent laterally to the plane ofthe plate. Engaging theseedge portions are edge portions 14 with which a connecting a plate 15 is provided. The connecting plate 15 with its edge portions 14 is made ofa single integral piece of sheet spring metal.`

Thus the two rocking plates 10 and 11 and the connecting plate act collectively as practically a single piece, pivoted at its center upon the bearing plate 9. There are two sets of the rocking plates 10 and 11 and the connecting plates 15. That is to say, these parts are duplicated at the ends of the ma'- chine. There are two blade holders 16 and k17, and these are adapted to carry razor blades L18 and 19. i f

Two rockers are shown yat 20 and 21 and are made of sheet kmeta-l so as to have a sub'- stantially semi-cylindrical form. These rockers are provided with end pieces 22 and and is provided with a y a pair ofV Arpair 23, the latter being mounted upon aY pair of shafts 25 and v26, each extending practically the full width of the machine. The

end pieces 22 and 23 carry pins 27, which f extend through slots 28 with which the rocking plates 10 are provided, as may be understood from Figure 2.

`A pair of casing members are shown at 29 and 30, and are pivotally mounted upon the bearing plate 9. `These casing members are of such form and size that they may be brought together face to face as indicated in Figures 1 and 2, and may be swung apart and brought together back to back as indicated in Figure 4. f

The casing members are provided with fastenings 31, 32 and 33, for holding them together in their different positions.

The casing members are further provided with guide rods 34. A pair of strops are shown at 35 and 36, and arranged as shown. One of these strops, say the one numbered 35, is made of leather, the other one being made of canvas. A pair of yokes 37 are connected with the rocking plate 10 and connecting plates 15, as indicated in Figure 3, for the purpose of'strengthening these parts and yet allowing them a slight de- .allow it a slight movement Within the casing. This causes the blade 19 to move slightly in a counter-clockwise direction according to this ligure, and thus be brought into engagement with the strop 36. The strops being nowV moved in the opposite direction, so as to'roclr the rocker 2l slightly in a counter-clockwise direction, a slight torque is produced in the rocking plates ll,

the result being that the blade 19 is there-` by forced to the left according to this figure, and into engagement with the adjacent surface of the strop 1.6. This stepis repeated as often as desired, the blade i9 thus being sharpened by means of the Vstrop 36.

Next the two casing members 29 and 30 are swung apart like the leaves of a book, the fastening members holding them together being disconnected for this purpose. This done the casing members are swung angularly around as indicated in Figure 4, the strops and various parts immediately associated therewith being now brought into positions indicated in Figure 6. The bail 7 is at practically Vthe same instantswung into its 'reverse position, as indicated in this figure. The bail 7 being now suspended Vfrom a n ail or the like, the machine is again ready for use. This time, however,

it is the blade 18 instead of theblade '19' which is in position to be acted upon by a strop, and' it is vthe strop 35 and not the strop 36 which is now adapted to be brought against the blade. The yoperator next, by drawing the, two strops as a unit back and forth, causes the strop 35 to act first on one side of 'the blade andthen upon the opposite side thereof, until the blade is sharpened, or otherwise in proper condition to be re moved. Y

In the particular use ofthe machine as just described, two razor blades are placed in position and are acted upon one at a time. However if the operator so prefers he .can insert a single blade only, and sharpen that blade, after which he can shift that blade from one of the blade holders to the other, and at the same ytime reverse the machine as above described in connection with Figure 4. This done, he can sharpen the same blade again, but with a strop different from the one he had first used upon that blade.

My device is made of materials readily produced in large quantities, and the various parts are of such form as to render them relatively easy to standardize. Moreover the device is quite well adapted for 'use with razor blades of kinds.

l do not limit myself to the precise construction shown, as variations may be made therein without departing from my invention, the scope of which is commensurateV with my claims. i

Having thus described my invention what l Vclaim as new and desire to secure by Letters Patent is as follows:

l. A razor double stropping machine comprising a pair of bladefholders extend-V ing in opposite directions, a pair of 'rock-i ing members connected with said blade holders for the purpose .of shifting the angular directions vin 'which' said -blade holders extend, a pair of strops, and means'controllable by the operator for bending said pair of strops aroundene ofsaid blade' holders in order to use one of said stropsv on a blade, and for bendingl said' pair "'o'f strops around the other of said-blade holders in order to use the other of said strops upon a blade. i

2. A device of the character described comprising a pair of casing members pivotally mounted to swing in opposite` direc.-L tions and thus brought togetheratone time face to face and at another vtime back't'o back, a pair of blade holderscommon `to said casing members', the casing members. being soconnected with the bladeiholders that either of said blade yholders maybe brought within the casing, a pairof-fstrops of `diierent character, each extending through both of said casing-members, so

. that the. swinging of said'k cas'i1i'g`"'members n carries one strop out'- of operative 'relation with one ofsaidblade *holders'and"carries the other of said strops into'operativ'el rela!I tion with the other of saidblade h'olders'f i 3. ln a device ofthe character described, the combination ofa pair'of casing Tinem bers pivotally connected in such mannen; that they may be brought together 'face'fto face or back to back, a p air of bla'deholders" connected with said casing members andf'so arranged that one of said blade 'holders iS enclosed by said casing members when7 brought together face to face, theother 'ofl said blade holders being enclosed bysaid casing members when .said casing members are brought together` back to back, a pair `of strops extending through said Vcasing mem.- bers in such manner that when said.casing", membersare brought together, face to vface one of the stropsis brought into `proximity to one of said blade holders, and when the members of said Acasing are brought `together vback to back the other ofsaid strops bought into proximity tothe othei` ofsaid blade holders, and apair ofrockingA devices Vso carried by said casing members and connected with said blade holders, and rocking devices being also connected with said strops, and controllable thereby for shifting the position of said blade holders relatively to said strops.

4. In a device of the character described the combination of a bail, a ypair of casing members mounted upon said bail and arranged to swing in opposite directions so that they can be brought together face to face or back to back, and razor stropping mechanism connected with said casing members and comprising a pair of blade holders and a pair of strops, both strops extending through the casing in vsuch manner that When the casing members are brought together face to face they enclose one of the blade holders, and when they are brought together back to back they enclose the other of said blade holders.

5. In a device of the character described the combination of a pair of blade holders extending in opposite directions, a pair of strops of dilerent character extending intermediate said blade holders, and means controllable by the operator for bending said pair of strops in opposite directions, so as to first bring one of the strops into proximity to one of the blade holders, and then to bring the other of said strops into proximity to the other of said blade holders.
